Subject: [PATCH] netlink: fix build warnings

Depending on compiler version and options, some of these warnings may
result in build failure.

- gcc 4.8 wants __KERNEL_DIV_ROUND_UP defined before including ethtool.h
- avoid pointer arithmetic on void *

Signed-off-by: Michal Kubecek <mkubecek@suse.cz>

[Patch was taken from the linux netdev mailinglist and will be applied in the
upcoming ethtool release 5.8]
